I'm looking for a high quality backpack sprayer between 3 and 4 gallons. I'm looking for one with the lever pump so I don't have to take it off my back.
I have two Solo units, one diaphram and one piston pump. The piston pump gets used probably 15 times a year to spray apple trees. I'm sure there a better and more epensive models out there but Solos work for me.
